Thread: Parallel inserts

Parallel inserts

From

Hi,

Assuming two or more clients issue INSERTs and COPYs on the same table
in the database at the same time, does PostgreSQL execute them in
parallel (i.e. no table-level locks, etc.) assuming there are no indexes
and constrains on the table? What about when there are indexes and/or
constraints?

Yes, parallel in all cases.
